Title: Imaging device
Inventor: MOTOHASHI SATORU
IPC: G03G15/02
Filed: 2001-03-12
Abstract: PROBLEM TO BE SOLVED: To provide high quality images at all times, stabilized by stabilizing dark potential on a photoreceptor drum, even when the AC component of a charged bias fluctuates. SOLUTION: When an AC component is controlled by a constant voltage method, a bias waveform is distorted on the upper limit side. Moreover, a cartridge load is caused to vary by environmental changes and endurance factors, therefore, the AC bias to be applied decreases as the cartridge load increases, and increases as the load decreases. Furthermore, the influence of the distortions on the upper limit side of the AC bias varies according to peak- to-peak voltages of the AC component, and the DC bias value thus becomes unstable. The DC component is stabilized, by making variable a resister 332 for deciding the DC component of a charged bias, and altering this resister, based on an output of a cartridge load detection circuit 203 for detecting combined static capacitance of the photoreceptor drum 101 and a charging roller 102.
